UNITED STATESPATENT OFFICE Application Noventa 21, 1935, serial No. 50,850 In France December 31, 1934 9 Claims. N(Cl. 88-16 My present invention relates to a photographic apparatus for taking on one and the same plate a certain number of photographic views arranged in rows and which may number forV example 63 (9 rows of 7 views). y

It has for itsobject to eiect the taking of different views lin a particularly rapid manner and to simplify the operations oi re-settlng to an appreciable extent.

With this object in view, my invention essentially consists in the special arrangements and combination of parts hereinafter fully described and pointed out in the claims.

On the annexed drawings:

Figure l is a rear elevational View of the apparatus;

Figure 2 is a section along,I Figure l.

Figure 3 is a substantially transverse sectional view taken on lines Ill-11i o Figure l.

The apparatus comprises a box, or frame I, for example of wood, which rests on a base 2 and which is divided into three compartments 3, 4, 5 by two vertical partitions 6 and 1.

The central compartment l contains a series of small cameras 41 which are placed side by side in the same horizontal line.

In the present case, these cameras are formed by two horizontal cross-members 8 and 3 (Fig- .ure 2) connected together by vertical partitions I0. t

Each camera is provided with a lens I I. All the lenses are mounted on a horizontal crossmember I 2.

The partitions are preferably so arranged that they converge slightly forwardly so as to obtain a good arrangement of the views. It is likewise possible to obtain the same result by lnclining the lateral lenses slightly towards the central lens.

Co-operating with each camera is a shutter I3 which is constituted by a single strip, for example of copper or aluminium, pierced by an aperture I4 and provided in its upper part with a flange I5 bent over at a right-angle, by means of which the shutters rest on a wooden ledge I6 which is adapted to slide horizontally by means of a knob I1 moving in a slot I8 (Figure l).

This ledge moves along the rear face of the apparatus in guides I9 and has a greater width in the part 20 which has to support the shutters I3. By the operation of the knob I 1 effecting the movement of the ledge I6, the shutters' I3 are released and fall successively. The successive fall of these shutters causes the apertures i4 the line H-II in to pass in front of the lenses, and thus determine the impression in successive places of the plate 23 which is held in guide grooves 24.

The plate 23 rests on a cross-member 25 which is likewise guided in grooves 24 and the function of which will be described hereinafter.

The raising of the shutters for re-setting the apparatus is ensured by a board 26 which extends over the entire length of the compartment Il and possesses in its lower part a butt 21 intended to act on the lower end of the shutter I3 when the latter has fallen. The said butt is generally provided with small springs for holding the shutters I3. Integral with this board 26 is a small box 261 divided into seven parts for the passage of the strips I3. Each part is in addition provided with an aperture acting as a diaphragm. The board 26 is securely fixed to a vertical rod 28 provided with an operating knob 29 and passing through guide orifices 33 provided respectively in a horizontal partition 3i of the conrpartment 3 and in the base 2. v

Furthermore, secured to the cross-member 25 is a small part 32 adapted to slide in a groove 33 provided in the rear face of the apparatus.

Fixed to the part 32 is a rack 34 which is provided in its lower portion with boards 35 and 36.

The rear face 31 of the apparatus is extended by two fiat members 38 which carry the board 35 and serve as a guide furthe lower end of the rack. l

Fixed `to board 35 is the end oi a spring 39 which winds around a small drum 40. Fixed to the rod 28 is a part 4I comprising an inclined plane 42 'with which co-operates a roller 43 xed to the end of a pawl 44, to which is articulated a lever 45v pivoted at 46 and carrying on its upper end a second pawl 41 subjected to the' action of a spring 48 fixed to the frame of the apparatus. The lever I5 is subjected to the action of a spring 49.

The operation of' the apparatus is as follows:

When it is desired to take a photograph, the shutters I3 and the plate 23 being in the position indicated in Figure 2, the operator, by means of the knob i1, moves the ledge yIii so as to cause the shutters I3 to fall successively and to impress the plate 23 along a band situated in its upper part. When this band has been impressed, the operator has to re-set the apparatus, that is to say, he has to return the shutters into the position of Figure 2 and raise the plate 23 by the height of one band; the raising of the shutters is ensured by raising by means of the knob 29, the rod 23 to which is secured the board 26 which, as already stated, acts on the lower part oi the shutters i3 and raises them all at the same time. "When the rod 28 has come to the end o' its upward stroke, the ledge i6 is again 5 moved so as to return the wide part 20 under the flanges of the shutters which are thus again supported; The rod 23 is then lowered again into its original position shown in Figure l.
